EUD - broken with above 1.16.1?

Hello folks, UMS mappers, map tool makers, EUD nerds!


I've tried and research about the status of EUDs in newer versions that 1.16.1 but couldn't find out what people mean with EUD being broken. It is understandable enough that the addresses change and you have to find the death table offsets all over again. So I've tried to use CheatEngine to do it myself.

I experimented with supply values of all three races:
1. There are values in Starcraft's memory I found that equal to the shown supply values in the in-game interface that change accordingly.
2. But these values have different addresses each game so it's impossible to use them as a reference in UMS mapping.
3. As it is stated in the SAN wiki, the in-game shown supply values are actually the internal values divided by 2, but I could not find any addresses with this pattern (I checked every value type and all races/supply values).
4. Assuming that the values I DID find (see my 1st point) are still calculated from the real internal supply values (I guess for String formatting or whatever) I can only deduct that these values I got are pretty useless.
5. So I've tried to track what writes to the addresses I found via Debugger in CheatEngine but then Starcraft crashes immediately - I suppose as a security measure against hacks.

So what gives? Is there now no actual way of accessing the memory through EUDs? Or did I do something wrong and the values I tried to find are out there but you "just" need to do some trick to find them?


Cheers!

I haven't delved into post-1.16.1 overflows at all, but a couple points about them in general.

EUD as a concept is a very hacky thing. The two main reasons they ever gained any popularity was 1) a client that did not change for a long time (i.e. no patches) and 2) the use of static memory addresses.

So even if one persisted enough to recalculate offsets for each patch, there's nothing one could do about the code changing to use dynamic memory addresses. A lot of effort for naught.

This is for EUD Conditions, not Actions. Actions will never be enabled on mainstream StarCraft.

So in your particular case, supply values they may or may not be held statically somewhere, but the motivation for investigating is pretty low.

Yes, I should have specified that I was talking about EUD Conditions to use in unaltered SC.

So I've found some addresses with Roy's tutorial that have supply values, but they behave like dynamic addresses. As I see it, there is no way to predict what specific address will be used for these values. A shame :/

Not to mention maps created with EUD are not player-centric at all.
1. EUD maps will not be playable on other versions.
2. EUD maps will not be playable on Mac.

These are not good experiences from a player's perspective.

To be fair, we had at least 2 cross-platformed EUD maps (EUD conditions->global actions) in 1.16 ;)

Can you still display leaderboard deaths for units by displaying kills of extended units (leaderboard kills of unit 229 should be deaths of terran marine, etc...)?

I don't think many useful EUDs change from version to version, as long as they keep the same structure.

The gas counters were broken in desert strike, so I assume they were changed if not restricted.

Good news it still works with the latest (1.20.3.2678 as of now) patch. Terran Marine deaths are UnitID:228 in Classic Trigedit, probably because of 0-based?

DarkenedFantasies -- Probably just didn't care. For example, at some point before release, they've updated the graphics of some of the Protoss buildings (Forge, CyberCore, Citadel, Observatory, Arbiter Tribunal), but instead of properly re-rendering them with edited 3D models, they did crappy copy-paste jobs on the rendered graphics.

Ultraviolet -- I suppose we'll likely never know, but my guess would be that they already saw it operating successfully and there was no monetary incentive to finish the original work. And the dev cycle in old school Blizzard was so hectic, it's possible it just got forgotten about after the original game got released. Plus there's an element of existing MPQ files that were packaged with the original discs becoming outdated if they updated it. And it's not like they remade the original MPQs, they just made new ones for BW specifically

Oh_Man -- so that makes me think maybe the theory they are unfinished is not true and its a deliberate design decision, coz why not finish them wen ur making brood war?
[2026-6-21. : 4:25 am]
Oh_Man -- the thing is thos buildings are from classic. that means they went ahead and made brood war without ever finishing the 'unfinished' buildings
[2026-6-20. : 6:15 pm]
Ultraviolet -- Yeah he's talked about a lot of that stuff in his casts before. It seems plausible. Especially knowing how Blizzard of yesteryear operated.
[2026-6-20. : 3:47 pm]
NudeRaider -- to clarify: couldn't recall the behavior for every single Protoss building but I was aware the disparity exists.
[2026-6-20. : 3:43 pm]
NudeRaider -- Contained nothing new for me. Didn't know all building's behavior, but very much all unit's. Also Terran balance whine - also nothing new :lol:
[2026-6-19. : 9:57 am]
Oh_Man -- makes me wonder if SEN knows anything about the topic
